Model & Applications Developer

About the role

The Model & Applications team develops and maintains first-principles mathematical models for simulating chemical process equipment. You will work on models that run in various modes including steady-state, dynamic, flow-driven, and pressure-driven simulation.

Responsibilities

• Develop, maintain, and improve first-principles mathematical models for simulating chemical process equipment in both steady-state and dynamic modes
• Implement model equations within a collaborative environment using standard Agile software development practices including version control, pull requests, and automated testing
• Diagnose and resolve complex simulation issues escalated from technical support, applying subject matter expertise to identify root causes
• Collaborate within multidisciplinary squads alongside software developers, thermodynamicists, and solver/optimization engineers to deliver new simulation capabilities

Requirements

• B.S., M.S., or Ph.D. in Chemical Engineering (or equivalent demonstrated experience in process modeling)
• Ability to derive and formulate systems of equations from first principles (mass, energy, and momentum balances)
• Strong foundation in transport phenomena and thermodynamics
• Familiarity with equation-oriented or simultaneous-equation solving approaches

Desired Skills And Competencies

• Experience with process simulation platforms (AVEVA, Aspen, etc.) and understanding solver convergence behavior
• Programming (Python, C++, C#, or similar) with experience working in a shared codebase using version control (e.g., Git)
• Breadth across multiple process domains (separations, reaction systems, heat exchange, pressure networks) with the ability to develop expertise in unfamiliar areas
• Ability to communicate complex mathematical and engineering concepts clearly to cross-functional stakeholders including developers, product managers, and customers
• A record of initiative and independent problem-solving: research contributions, open-source development, or self-directed technical projects
